The ABB Ultra-Fast Earthing Switch (UFES) is a cutting-edge active arc fault protection system designed to protect personnel and electrical equipment from the destructive effects of internal arc faults. By rapidly grounding the system, the UFES extinguishes an arc fault in less than 4 milliseconds, significantly reducing the incident energy released. To find a specific manual: : These are

The mechanical UFEA actuators are . Once the micro-gas generator has fired and the pin has entered the vacuum chamber, the actuator cannot be reset in the field. Once the micro-gas generator has fired and the

UFES offers two control‑unit options, each with its own manual section and configuration method:

The ABB UFES manual highlights several benefits that engineers and project managers can expect from using this platform:
